The MPI implementation is openmpi 1.4.2_0+gcc43 installed with macports.
And it seems that I have it installed in two places
/usr/include/openmpi/ompi/mpi/cxx/ /opt/local/include/openmpi/openmpi/ompi/mpi/cxx/
There is nothing wrong with installing multiple versions, but care should then be taken that they are not mixed up. This is what could be happening here (just a guess).
If you don't really need two installed versions I would first uninstall one of the two and try again, from scratch.
